This recipe by Jonathan Rassi, chef and instructor at the ITHQ, highlights sea bass, a lean white fish known for its delicate flavour. Cook the fillets in the oven on a bed of kale, along with squash, sweet potato, Brussels sprouts and cherry tomatoes. Serve with a bright topping made of lemon, olives and capers to revive the fish and roasted vegetables for a touch of saltiness and tang. It's a colourful and easy-to-prepare dish you'll want to make again and again.
